(16 votes, average: 3.63 out of 5)A Bear has fallen from a height of 10m from ground. It reached ground in sqrt(2) seconds. Luckily it didn’t get hurt.
What is the color of that Bear? Prove it scientifically.

As s = ut + (1/2)at^2
Here s = 10, u = 0, t =√2
Putting these values, a = 10
So, a = g = 10
This value of g is the maximum value and is at the poles as the value of g increases from equator to poles.

Hence, its on pole so a white polar bear

In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level effective gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh about 0.5% more at the poles than at the Equator.
Taking value of gravity at Polar region as 9.8 =~ 10.Applying newtons second equation of motion(s=ut+1/2at^2), times comes to be sqrt(2).Hence bear belongs to polar region,hence it shuold be white in color.
what is the value of ‘u’ here, then?
u will be 0…!!!
white
brown teddy bear
The bear is nonexistent and so no color. g = 10 is nowhere on the surface of earth. Event at the polar regions. If there was a very deep hole in the polar region and the bear was inside the hole this question would have been correct. Then the color would be white.

maybe, maybe not. the poles are closer to the core of the earth hence gravity is more than 9.8 but is it 10? if it is 10, then the bear is white (polar bear) and only if its the north pole.
